Description of Business and Summary of Significant Accounting Policies
Description of Business and Summary of Significant Accounting Policies	1. Description of Business and Summary of Significant Accounting Policies Description of Business Iteris, Inc. (referred to collectively with its subsidiary in these consolidated financial statements as "Iteris," the "Company," "we," "our" and "us") is a provider of intelligent information solutions for both the traffic management and global agribusiness markets. We are focused on the development and application of advanced technologies and software-based information systems that reduce traffic congestion, provide measurement, management and predictive traffic and weather analytics, and improve the safety of surface transportation systems infrastructure. By combining our unique intellectual property, products, decades of experience in traffic management, weather forecasting solutions and information technologies, we offer a broad range of Intelligent Transportation Systems ("ITS") solutions to customers throughout the U.S. and internationally. In the agribusiness markets, we have combined our intellectual property with enhanced soil, land surface and agronomy modeling techniques to create a set of ClearAg solutions. These solutions provide analytical software solutions to large and small enterprises in the global agriculture market. We continue to make significant investments to leverage our existing technologies and further expand our software-based information systems to offer solutions to the precision agriculture technology markets. Iteris was incorporated in Delaware in 1987. In March 2017, our subsidiary, Iteris Michigan LLC, was dissolved as a legal entity and ceased operating as a wholly-owned subsidiary of the Company. Basis of Presentation Our consolidated financial statements include the accounts of Iteris, Inc. and its subsidiary and have been prepared in accordance with generally accepted accounting principles in the United States of America ("GAAP"). All intercompany accounts and transactions have been eliminated in consolidation. The results of continuing operations for all periods presented in the consolidated financial statements exclude the financial impact of a discontinued operation. See Note 3, "Sale of Vehicle Sensors," for further discussion related to the discontinued operation presentation. Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires our management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements, and reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant estimates made in the preparation of the consolidated financial statements include the collectability of accounts receivable and related allowance for doubtful accounts, projections of taxable income used to assess realizability of deferred tax assets, warranty reserves, costs to complete long-term contracts, indirect cost rates used in cost-plus contracts, contract reserves, the valuation of purchased intangible assets and goodwill, the valuation of equity instruments and estimates of future cash flows used to assess the recoverability of long-lived assets and the impairment of goodwill and fair value of our stock option awards used to calculate the stock-based compensation. Revenue Recognition Product revenues and related costs of sales are recognized when all of the following criteria are met: (i) persuasive evidence of an arrangement exists, (ii) delivery under the terms of the arrangement has occurred, (iii) the price to the customer is fixed or determinable, and (iv) collection of the receivable is reasonably assured. These criteria are typically met at the time of product shipment but, in certain circumstances, may not be met until receipt or acceptance by the customer. Accordingly, at the date revenue is recognized, the significant obligations or uncertainties concerning the sale have been resolved. Transportation Systems revenues are derived primarily from long-term contracts with governmental agencies. Certain Agriculture and Weather Analytics revenues are also derived from long-term contracts with governmental agencies, as well as contracts with commercial companies. Agriculture and Weather Analytics revenues that are derived from contracts with commercial companies are from subscription revenue that we typically invoice our customers at the beginning of the term, in multiyear, annual, semi-annual or quarterly installments and revenue is recognized ratably over the period of the subscription beginning once all requirements for revenue recognition have been met, including provisioning the service so that it is available to our customers. When appropriate, revenues are recognized using the percentage of completion method of accounting, whereby revenue is recognized as contract performance progresses and is determined based on the relationship of costs incurred to total estimated costs. Any anticipated losses on contracts are charged to earnings when identified. Changes in job performance and estimated profitability, including those arising from contract penalty provisions and final contract settlements, may result in revisions to costs and revenues, and are recognized in the period in which the revisions are determined. Profit incentives are included in revenues, when their realization is reasonably assured. Certain of our revenues are recognized as services are performed and amounts are earned, which is measured by time incurred or other contractual milestones or output measures. Revenues accounted for in this manner generally relate to certain fixed fee professional services, cost plus fixed fee or time and materials contracts. Revenues for ongoing operations and maintenance services contracts are generally accounted for ratably as the services are performed throughout the term of the contract. Payments received in advance of services performed are deferred and recognized when the related services are performed. We recognize revenue from the sale of deliverables that are part of a multiple element arrangement in accordance with applicable accounting guidance that establishes a relative selling price hierarchy permitting the use of an estimated selling price to determine the allocation of arrangement consideration to a deliverable in a multiple element arrangement where neither vendor specific objective evidence ("VSOE") nor third party evidence ("TPE") of fair value is available for that deliverable. In the absence of VSOE or TPE of the stand-alone selling price for one or more delivered or undelivered elements in a multiple element arrangement, we are required to estimate the selling prices of those elements. Overall arrangement consideration is allocated to each element (both delivered and undelivered items) that has stand-alone value based on their relative selling prices, regardless of whether those selling prices are evidenced by VSOE or TPE or are based on our estimated selling prices. Unbilled Accounts Receivable Unbilled accounts receivable in the accompanying consolidated balance sheets represent unbilled amounts earned and reimbursable under services sales arrangements, including approximately $362,000 of costs and estimated earnings in excess of billings on uncompleted contracts accounted for under Financial Accounting Standards Board ("FASB") Accountind Standards Codification ("ASC") 605-35, Construction-Type and Production-Type Contracts . At any given period-end, a large portion of the balance in this account represents the accumulation of labor, materials and other costs that have not been billed due to timing, whereby the accumulation of each month's costs and earnings are not administratively billed until the subsequent month. Also included in this account are amounts that will become billable according to contract terms, which usually require the consideration of the passage of time, achievement of milestones or completion of the project. Deferred Revenue Deferred revenue in the accompanying consolidated balance sheets is comprised of cash collected from customers and billings to customers on contracts in advance of work performed, advance payments negotiated as a contract condition, estimated losses on uncompleted contracts, project-related legal liabilities and other project-related reserves, including approximately $798,000 of billings in excess of costs and estimated earnings on uncompleted contracts accounted for under FASB ASC 605-35. The unearned amounts are expected to be earned within the next twelve months. We record provisions for estimated losses on uncompleted contracts in the period in which such losses become known. The cumulative effects of revisions to contract revenues and estimated completion costs are recorded in the accounting period in which the amounts become evident and can be reasonably estimated. These revisions can include such items as the effects of change orders and claims, warranty claims, liquidated damages or other contractual penalties and adjustments for contract closeout settlements. Concentration of Credit Risk Financial instruments that potentially subject us to a concentration of credit risk consist principally of cash and cash equivalents and trade accounts receivable. Cash and cash equivalents consist primarily of demand deposits and money market funds maintained with several financial institutions. Deposits held with banks may exceed the amount of insurance provided on such deposits. Generally, these deposits may be redeemed upon demand and are maintained with high quality financial institutions, and therefore are believed to have minimal credit risk. Our accounts receivable are primarily derived from billings with customers located throughout North America, as well as in the Middle East, Europe, South America and Asia. We generally do not require collateral or other security from our domestic customers. We maintain an allowance for doubtful accounts for potential credit losses, which losses have historically been within management's expectations. We have historically had a diverse customer base. For the fiscal year ended March 31, 2017 ("Fiscal 2017"), one individual customer represented greater than 10% of our total revenues. For the fiscal year ended March 31, 2016 ("Fiscal 2016") and the fiscal year ended March 31, 2015 ("Fiscal 2015"), no individual customer represented more than 10% of our total revenues. Fair Values of Financial Instruments The fair value of cash equivalents, receivables, accounts payable and accrued expenses approximate carrying value because of the short period of time to maturity. Cash and Cash Equivalents Cash and cash equivalents consist of cash and short-term investments with initial maturities of ninety days or less. Prepaid Expenses and Other Current Assets Prepaid expenses and other current assets were $2.1 million as of March 31, 2017 and $1.5 million as of March 31, 2016 and included approximately $535,000 of cash designated as collateral on performance bonds, as required under certain of our Transportation Systems contracts in the Middle East. The performance bonds require us to maintain 100% cash value of the bonds as collateral in a bank that is local to the purchasing agency. The performance bond collateral is required throughout the delivery of our services and is maintained in the local bank until the contract is closed by the purchasing agency. We expect these requirements, and the related cash collateral restrictions, to be released during 2017. Allowance for Doubtful Accounts The collectability of our accounts receivable is evaluated through review of outstanding invoices and ongoing credit evaluations of our customers' financial condition. In cases where we are aware of circumstances that may impair a specific customer's ability to meet its financial obligations subsequent to the original sale, we will record an allowance against amounts due, and thereby reduce the net recognized accounts receivable to the amount we reasonably believe will be collected. We also maintain an allowance based on our historical collections experience. When we determine that collection is not likely, we write off accounts receivable against the allowance for doubtful accounts. Inventories Inventories consist of finished goods, work-in-process and raw materials and are stated at the lower of cost or market. Cost is determined using the first-in, first-out method. Property and Equipment Property and equipment are recorded at cost and are depreciated using the straight-line method over the estimated useful life ranging from three to eight years. Leasehold improvements are depreciated over the term of the related lease or the estimated useful life of the improvement, whichever is shorter. Goodwill and Long-Lived Assets We evaluate goodwill on an annual basis in our fourth fiscal quarter or more frequently if we believe indicators of impairment exist. We have determined that our reporting units for purposes of testing for goodwill impairment are identical to our reportable segments for financial reporting purposes. We first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If we conclude that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, we conduct a goodwill impairment test. The impairment test involves comparing the fair values of the applicable reporting units with their carrying values. We determine the fair values of our reporting units using the income valuation approach, as well as other generally accepted valuation methodologies. In Fiscal 2017, we adopted the provisions issued by the FASB that were intended to simplify goodwill impairment testing. This guidance permits us to eliminate the second step of the goodwill impairment test, and eliminate the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment. If the carrying amount of a reporting unit exceeds the reporting unit's fair value, the amount by which the carrying value of the goodwill exceeds its implied fair value, if any, is recognized as an impairment loss. We monitor the indicators for goodwill impairment testing between annual tests. As of March 31, 2017, we determined the carrying amount of the goodwill in the Agriculture and Weather Analytics reporting unit exceeded it's implied fair value, and as a result, recognized an approximate $2.2 million impairment loss in the accompanying consolidated financial statements. We also determinted that no adjustments to the carrying value of its goodwill and intangible assets were required in the Roadway Sensors and Transportation Systems reporting units. We test long-lived assets and purchased intangible assets (other than goodwill) for impairment if we believe indicators of impairment exist. We determine whether the carrying value of an asset or asset group is recoverable, based on comparisons to undiscounted expected future cash flows the asset or asset group is expected to generate. If an asset is not recoverable, we record an impairment loss equal to the amount by which the carrying value of the asset exceeds its fair value. We primarily use the income valuation approach to determine the fair value of our long lived assets and purchased intangible assets. As of March 31, 2017, there was no impairment to our long-lived and intangible assets. Income Taxes We utilize the asset and liability method of accounting for income taxes, under which deferred taxes are determined based on the temporary differences between the financial statement and tax basis of assets and liabilities using tax rates expected to be in effect during the years in which the basis differences reverse. A valuation allowance is recorded when it is more-likely-than-not that some or all of the deferred tax assets will not be realized, which increases our income tax expense in the period such determination is made. As such, we determined it was appropriate to record a valuation allowance of approximately $10.1 million in the third quarter of our Fiscal 2016 against our deferred tax assets. We will continuously reassess the appropriateness of maintaining a valuation allowance. Income tax positions must meet a more-likely-than-not recognition threshold to be recognized. Income tax positions that previously failed to meet the more-likely-than-not threshold are recognized in the first subsequent financial reporting period in which that threshold is met. Previously recognized tax positions that no longer meet the more-likely-than-not threshold are derecognized in the first subsequent financial reporting period in which that threshold is no longer met. Stock-Based Compensation We record stock-based compensation in our consolidated statements of operations as an expense, based on the estimated grant date fair value of our stock-based awards, whereby such fair values are amortized over the requisite service period. Our stock-based awards are currently comprised of common stock options and restricted stock units. The fair value of our common stock option awards is estimated on the grant date using the Black-Scholes-Merton option-pricing formula. While utilizing this model meets established requirements, the estimated fair values generated by it may not be indicative of the actual fair values of our common stock option awards as it does not consider certain factors important to those awards to employees, such as continued employment and periodic vesting requirements, as well as limited transferability. The fair value of our restricted stock units is based on the closing market price of our common stock on the grant date. If there are any modifications or cancellations of the underlying unvested stock-based awards, we may be required to accelerate, increase or cancel any remaining unearned stock-based compensation expense. Research and Development Expenditures Research and development expenditures are charged to expense in the period incurred. Shipping and Handling Costs Shipping and handling costs are included as cost of revenues in the period during which the products ship. Sales Taxes Sales taxes are presented on a net basis (excluded from revenues) in the consolidated statements of operations. Advertising Expenses Advertising costs are expensed in the period incurred and totaled $146,000, $164,000 and $134,000 in Fiscal 2017, Fiscal 2016 and Fiscal 2015, respectively. Warranty We generally provide a one to three year warranty from the original invoice date on all products, materials and workmanship. Products sold to various original equipment manufacturer customers sometimes carry longer warranties. Defective products will be either repaired or replaced, usually at our option, upon meeting certain criteria. We accrue a provision for the estimated costs that may be incurred for product warranties relating to a product as a component of cost of sales at the time revenue for that product is recognized. The accrued warranty reserve is included within accrued liabilities in the accompanying consolidated balance sheets. Repair and Maintenance Costs We incur repair and maintenance costs in the normal course of business. Should the repair or maintenance result in a permanent improvement to one of our leased facilities, the cost is capitalized as a leasehold improvement and amortized over its useful life or the remainder of the lease period, whichever is shorter. Non-permanent repair and maintenance costs are charged to expense as incurred. Comprehensive Income Comprehensive income equals net income for all periods presented. Recent Accounting Pronouncements In May 2014, the FASB issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers ("ASU 2014-09"), which establishes principles for reporting revenue and cash flows arising from an entity's contracts with customers. This new revenue recognition standard will replace most of the recognition guidance within GAAP. This guidance was deferred by ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date, issued by the FASB in August 2015, and is now effective for fiscal years beginning on or after December 15, 2017 with early adoption permitted as of the original effective date. In March 2016, the FASB issued ASU No. 2016-08, Revenue from Contracts with Customers: Principal versus Agent Considerations , which further clarifies the implementation guidance in ASU 2014-09. In April 2016, the FASB issued ASU No. 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing , to expand the guidance on identifying performance obligations and licensing within ASU 2014-09. In May 2016, the FASB issued ASU 2016-12, Revenue from Contracts with Customers: Narrow-Scope Improvements and Practical Expedients , which amends the guidance in the new revenue standard on collectability, noncash consideration, presentation of sales tax, and transition. The amendments are intended to address implementation issues that were raised by stakeholders and provide additional practical expedients to reduce the cost and complexity of applying the new revenue standard. These standards are effective for fiscal years beginning after December 15, 2017, including interim periods within that reporting period. We anticipate that these standards will have an impact on our consolidated financial statements and we are still evaluating the significance of the impact. In July 2015, the FASB issued ASU No. 2015-11, Simplifying the Measurement of Inventory ("ASU 2015-11") to simplify the guidance on the measurement of inventory. Under the new standard, an entity should measure inventory at the lower of cost or net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The standard is effective for interim and annual periods beginning after December 15, 2016. We do not anticipate a significant impact on our consolidated financial statements upon adoption of ASU 2015-11. In November 2015, the FASB issued ASU No. 2015-17, Balance Sheet Classification of Deferred Taxes ("ASU 2015-17") to simplify the presentation of deferred taxes by requiring deferred tax assets and liabilities be classified as noncurrent on the balance sheet. ASU 2015-17 is effective for public companies for annual reporting periods beginning after December 15, 2016, and interim periods within those fiscal years. The standard may be adopted prospectively or retrospectively and early adoption is permitted. We early adopted ASU 2015-17, prospectively, in our fourth quarter of Fiscal 2016, which did not have a material impact on our consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases ("ASU 2016-02"). The pronouncement requires an entity to recognize assets and liabilities for the rights and obligations created by leases on the entity's balance sheet for both finance and operating leases. For leases with a term of 12 months or less, an entity can elect to not recognize lease assets and lease liabilities and expense the lease over a straight-line basis for the term of the lease. ASU 2016-02 will require new disclosures that depict the amount, timing, and uncertainty of cash flows pertaining to an entity's leases. Companies are required to adopt the new standard using a modified retrospective approach for annual and interim periods beginning after December 15, 2018. Early adoption of ASU 2016-02 is permitted. We are currently evaluating the impact of ASU 2016-02 on our consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-09, Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting ("ASU 2016-09"), which is intended to simplify several aspects of accounting for share-based compensation arrangements, including the income tax impact, classification on the statement of cash flows and forfeitures. The guidance will be effective for the fiscal year beginning after December 15, 2016, including interim periods within that year. We are currently evaluating the impact of ASU 2016-09 on our consolidated financial statements. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments ("ASU 2016-15"), which clarifies how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The new standard is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017, and early adoption is permitted. We are currently evaluating the impact of ASU 2016-15 on our consolidated financial statements. In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash ("ASU 2016-18"), requiring restricted cash and cash equivalents to be included with cash and cash equivalents on the statement of cash flows. The new standard is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017, with early adoption permitted. We are currently evaluating the impact of ASU 2016-18 on our consolidated financial statements. In December 2016, the FASB issued ASU No. 2016-19, Technical Corrections and Improvements ("ASU 2016-19"), which clarifies guidance, corrects errors and makes minor improvements affecting a variety of topics in the ASC. The new standard is effective upon issuance (December 14, 2016) for amendments that do not have transition guidance, with all other amendments effective for fiscal years, and interim periods within those years, beginning after December 15, 2016, with early adoption permitted. We are currently evaluating the impact of ASU 2016-19 on our consolidated financial statements. In December 2016, the FASB issued ASU No. 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers ("ASU 2016-20"), which allows entities not to make quantitative disclosures about remaining performance obligations in certain cases and requires entities that use any of the new or previously existing optional exemptions to expand their qualitative disclosures. The new standard is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017, with early adoption permitted. We are currently evaluating the impact of ASU 2016-20 on our consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment ("ASU 2017-04"), eliminating the second step of the goodwill impairment test, and eliminating the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment. The new standard is effective for fiscal years, and interim periods within those years, beginning after December 15, 2019, with early adoption permitted. We chose to early adopt ASU 2017-04 in our fourth quarter of Fiscal 2017, which had an impact on our consolidated financial statements, as we recognized a goodwill impairment loss in our Agriculture and Weather Analytics reporting unit.

Sale of Vehicle Sensors	3. Sale of Vehicle Sensors On July 29, 2011, we completed the sale of substantially all of our assets used in connection with our prior Vehicle Sensors segment to Bendix Commercial Vehicle Systems LLC ("Bendix"), a member of Knorr-Bremse Group. In connection with the asset sale, we are entitled to additional consideration in the form of the following performance and royalty-related earn-outs: Bendix is obligated to pay us an amount in cash equal to 85% of revenue associated with royalties received under our license and distribution agreements with Audiovox Electronics Corporation and Valeo Schalter and Sensoren GmbH through December 31, 2017, subject to certain reductions and limitations set forth in the asset purchase agreement. From the date of the asset sale, through March 31, 2017, we received approximately $2.1 million in connection with royalty-related earn-outs provisions for a total of $17.4 million in cash from the asset sale. In accordance with applicable accounting guidance, we determined that the Vehicle Sensors segment, which constituted one of our operating segments, qualified as a discontinued operation. For the fiscal year ended March 31, 2017, 2016 and 2015, we recorded a gain on sale of discontinued operation of approximately $361,000, $214,000 and $207,000, respectively, net of tax, related to the earn-out provisions of the asset purchase agreement.

Acquisitions	4. Acquisitions Berkeley Transportation Systems, Inc. In the fiscal year ended March 31, 2012 ("Fiscal 2012"), we acquired all of the outstanding capital stock of Berkeley Transportation Systems, Inc. ("BTS"). BTS was a privately-held company based in Berkeley, California, which specialized in transportation performance measurement. BTS' Performance Measurement System leverages its real-time data collection, diagnostic, fusion and warehousing platform to aggregate and compute performance measures. This information is used to analyze how a transportation system is performing based on pre-determined measures of effectiveness such as stops, delays and travel time. Our primary reasons for the acquisition were to add key technologies to complement our iPeMS solutions and strengthen our performance measurement and management initiative as a whole. Our consolidated financial statements for Fiscal 2017, Fiscal 2016 and Fiscal 2015 include the results of operations of BTS. On or shortly after the acquisition date, we paid a total of approximately $840,000 in cash to the shareholders of BTS. On December 17, 2012, the Company entered into an amendment to the BTS stock purchase agreement, which modified certain earn out provisions, and as a result, the Company paid $700,000 in cash to the former BTS shareholders for achievement of those modified earn-out provisions in our fourth quarter of the fiscal year ended March 31, 2013 ("Fiscal 2013"). The amendment did not have a material impact on previous estimated amounts accrued in connection with the earn-out provisions. This payment completed the Company's obligation under the earn- out provisions of the agreement. During the third quarter of the fiscal year ended March 31, 2014 ("Fiscal 2014"), the Company paid $250,000 pursuant to certain holdback provisions. Additionally, the Company paid the BTS shareholders approximately $336,000 in November 2014 pursuant to certain deferred payment provisions. These payments completed all of the Company's obligations under the purchase agreement.

Impairment of Goodwill
Impairment of Goodwill	5. Impairment of Goodwill As discussed in Note 1, goodwill is tested for impairment on an annual basis in our fourth fiscal quarter or more frequently if indicators of impairment exist. Based on our goodwill impairment testing for Fiscal 2017, we believe the carrying value of our goodwill in our Agriculture and Weather Analytic reporting unit was impaired as of March 31, 2017, and resulted in approximately $2.2 million impairment charge. We also determined our Roadway Sensors and Transportation Systems reporting units were not impaired as of March 31, 2017. Based on our goodwill impairment testing for Fiscal 2016 and 2015, we believe the carrying value of our goodwill was not impaired, as the estimated fair values of our reporting units exceeded their carrying values at the end of such fiscal years. If our actual financial results, or the plans and estimates used in future goodwill impairment analyses, are lower than our original estimates used to assess impairment of our goodwill, we could incur goodwill impairment charges in the future.

Fair Value Measurements

Fair Value Measurements
Fair Value Measurements	6. Fair Value Measurements We measure fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Fair value measurements are based on a three-tier hierarchy that prioritizes the inputs used to measure fair value. These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets for identical assets and liabilities; Level 2, defined as observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities or prices quoted in inactive markets; and Level 3, defined as unobservable inputs that are significant to the fair value of the asset or liability, and for which little or no market data exists, therefore requiring management to utilize its own assumptions to provide its best estimate of what market participants would use in valuing the asset or liability. We did not have any material financial assets or liabilities measured at fair value on a recurring basis using Level 3 inputs as of March 31, 2017 or 2016. Our non-financial assets, such as goodwill, intangible assets and property and equipment, are measured at fair value on a non-recurring basis, generally when there is a transaction involving those assets such as a purchase transaction, a business combination or an adjustment for impairment. In Fiscal 2017, Level 3 inputs were used to evaluate the fair value of our goodwill in our three reporting units. As a result of our impairment testing, we recorded an adjustment for impairment of approximately $2.2 million in our Agriculture and Weather Analytics reporting unit. No other non- financial assets were measured at fair value during the fiscal years ended March 31, 2017, 2016, and 2015.

We also had $555,000 in state tax credits that begin to expire in 2023. We had $5.6 million of federal net operating loss carryforwards at March 31, 2017 that begin to expire in 2022. We also had $1.4 million of state net operating loss carryforwards at March 31, 2017 that begin to expire in 2031. Our deferred tax assets at March 31, 2017 do not include approximately $1.1 million of excess tax benefits from employee stock option exercises that are a component of our net operating loss carryforwards. If and when such excess tax benefits are realized, stockholders' equity will be increased. In assessing the realizability of our deferred tax assets, we review all available positive and negative evidence, including reversal of deferred tax liabilities, potential carrybacks, projected future taxable income, tax planning strategies and recent financial performance. As of December 31, 2015, the Company had generated a cumulative pre-tax loss over the trailing three years. As such, we considered it appropriate to record a valuation allowance of approximately $10.1 million in our third quarter of Fiscal 2016 against our deferred tax assets. We will continuously reassess the appropriateness of maintaining a valuation allowance. Unrecognized Tax Benefits As of March 31, 2017 and 2016, our gross unrecognized tax benefits were $426,000 and $394,000, respectively, of which $286,000 and $251,000, respectively, are netted against certain noncurrent deferred tax assets. The amounts that would affect our effective tax rate if recognized are $359,000 and $328,000, respectively. We recognize interest and/or penalties related to income tax matters in income tax expense. As of March 31, 2017 and 2016, we had accrued cumulatively $46,000 and $52,000, respectively, for the payment of potential interest and penalties. The total amount of interest and penalties recognized in the consolidated statements of operations for the fiscal years ended March 31, 2017 and 2016 was $(6,000) and $5,000, respectively. A reconciliation of the beginning and ending balances of the total amounts of gross unrecognized tax benefits is as follows: Year Ended March 31, 2017 2016 2015 (In thousands) Gross unrecognized tax benefits at beginning of year $ $ $ Increases for tax positions taken in prior years Decreases for tax positions taken in prior years ) — ) Increases for tax positions taken in the current year Lapse in statute of limitations ) ) ) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Gross unrecognized tax benefits at March 31 $ $ $ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ We do not anticipate a significant change in gross unrecognized tax benefits within the next twelve months. We are subject to taxation in the U.S. and various state tax jurisdictions. We are subject to U.S. federal tax examination for fiscal tax years ended March 31, 2014 or later, and state and local income tax examination for fiscal tax years ended March 31, 2013 or later. However, if NOL carryforwards that originated in earlier tax years are utilized in the future, the amount of such NOLs from such earlier years remain subject to review by tax authorities.

Commitments and Contingencies	9. Commitments and Contingencies Litigation and Other Contingencies As a provider of traffic engineering services, hardware products, software and other various solutions for the traffic and agricultural industries, the Company has in the past been, and may in the future be from time to time, involved in litigation relating to claims arising out of its operations in the normal course of business. While the Company cannot accurately predict the outcome of any such litigation, except as described below, the Company is not a party to any legal proceeding, the outcome of which, in management's opinion, individually or in the aggregate, would have a material effect on the Company's consolidated results of operations, financial position or cash flows. On September 15, 2016, a stockholder class action and derivative action (captioned Ionni v. Bergera, et al., Case No. 16-cv00807-RGA) was filed in the United States District Court for the District of Delaware (the "Court") against certain of the Company's current and former directors and officers (the "Individual Defendants") and the Company as a nominal defendant (together with the Individual Defendants, the "Defendants"). The complaint asserts claims for breach of fiduciary duty and unjust enrichment. Plaintiff contends that, in 2014 and 2015, the Individual Defendants caused the Company to issue purportedly false and misleading proxy statements in connection with the Company's annual meeting of stockholders in 2014 and 2015 (collectively, the "Proxy Statements"). In those Proxy Statements, the Company's stockholders were asked to approve amendments (the "Amendments") to increase the number of shares of the Company's common stock reserved for issuance under the Iteris, Inc. 2007 Omnibus Incentive Plan (the "2007 Plan"). Among other things, Plaintiff alleges that the Proxy Statements were materially false and misleading because they affirmatively represented that no person could receive more than 500,000 stock options or SARs under the 2007 Plan in any fiscal year (the "Share Limit") and failed to disclose that the Compensation Committee had the discretion to approve an annual grant to a 2007 Plan participant in excess of that amount. Plaintiff contends that, in voting to approve the Amendments, the Company's stockholders were not fully informed and, therefore, the Amendments were not valid. Plaintiff seeks rescission of any stock options granted pursuant to the Amendments, including the option to purchase up to 1,350,000 shares of the Company's common stock that was granted in September 2015 to Mr. Bergera (the "CEO Option") in connection with his appointment to serve as President and Chief Executive Officer of the Company. The Individual Defendants deny that they breached their fiduciary duties and the Company believes the Amendments were properly approved and that all of the options granted pursuant to the Amendments, including the CEO Option, were valid. Nonetheless, to eliminate the burden, expense and uncertainty of the litigation, on November 8, 2016, the parties entered into a Memorandum of Understanding ("MOU") setting forth their agreement in principle to resolve the litigation. In consideration for a release of claims and dismissal of this litigation with prejudice, the Company agreed to submit a proposal at its 2016 Annual Meeting of Stockholders seeking stockholder approval for that portion of the CEO Option that exceeds the Share Limit (i.e., the 850,000 options above the Share Limit (the "Excess Shares")). The Company submitted a proposal of the Excess Shares for approval by the Company stockholders at the 2016 Annual Meeting of Stockholders. On December 15, 2016, the Company's stockholders approved the Excess Shares. On April 28, 2017, the parties entered into a Stipulation of Settlement and Compromise (the "Stipulation") that provides for, among other things, a release of claims against Defendants. Under the Stipulation, Defendants agreed not to oppose any award of attorneys' fees and expenses to Plaintiff up to $215,000. On May 2, 2017, the parties filed a motion for preliminary approval of the settlement. On May 11, 2017, the Court issued an order requesting briefing from the parties regarding the scope of the proposed release in the settlement, and on May 22, 2017, Defendants and Plaintiff each filed a letter brief to the Court in response to the order. On June 2, 2017, the Court issued an Order granting the motion for preliminary approval, approving notice of the settlement, and scheduling a settlement approval hearing for September 8, 2017. We recorded an immaterial accrued liability for the settlement in the accompanying consolidated balance sheet as of March 31, 2017. Operating Leases In May 2007, we entered into an agreement to lease 52,000 square feet of office space in Santa Ana, California for a term of 88 months. In September 2007, we relocated our headquarters and principal operations into this space. The monthly lease rate was $102,000 during the first year of the lease and increased each year thereafter, to $120,000 per month during the last year of the lease. In February 2014, we entered into an amendment to the lease, which reduced our office space by approximately 11,000 square feet and changed the lease term to 96 months, commencing on April 1, 2014. The monthly lease rate is approximately $76,000 during the first year of the amended term and increases each year thereafter, up to a maximum of approximately $90,000 during the last year of the term. Additionally, the lease amendment provided for approximately $328,000 in incentives in the form of tenant improvement allowances, which we recorded as fixed assets and deferred rent in our consolidated balance sheet. The leasehold improvements were capitalized into fixed assets during Fiscal 2015 and will be depreciated over the estimated useful life of the improvements, or the term of the lease amendment, whichever is shorter. The corresponding deferred rent amount will reduce monthly rent expense over the term of the lease amendment. On January 23, 2017, we entered into an amendment to the lease, which added approximately 5,980 square feet and will expire after 60 months, commencing on April 1, 2017. The monthly lease rate is approximately $14,000 during the first year of the term and increase each year thereafter, up to a maximum of approximately $16,000 during the last year of the term. Additionally, the lease amendment provided for approximately $119,000 in incentives in the form of tenant improvement allowances. We have lease commitments for facilities in various locations throughout the U.S., as well as for certain equipment. Future minimum rental payments under these non-cancelable operating leases at March 31, 2017 were as follows: Year Ending March 31, 2018 $ 2019 2020 2021 2022 Thereafter ​ ​ ​ ​ ​ $ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Rent expense totaled approximately $1.7 million for each of Fiscal 2017, Fiscal 2016 and Fiscal 2015. Related Party Transaction We previously subleased office space to Maxxess Systems, Inc. ("Maxxess"), one of our former subsidiaries that we sold in September 2003. The sublease terminated in September 2007, at which time Maxxess owed us an aggregate of $274,000. Maxxess executed a promissory note for such amount, which was subsequently amended and restated on July 23, 2013. The amended and restated note bears interest at a rate of 6% per annum, compounded annually, with accrued interest payable quarterly on the first business day of each calendar quarter. Maxxess continues to pay down the balance of this note by providing consulting services to Iteris, although we have previously fully reserved for amounts owed to us by Maxxess and the outstanding principal balance remains fully reserved. As of March 31, 2017, approximately $146,000 of the original principal balance was outstanding and payable to Iteris. Maxxess is currently owned by an investor group that includes one former Iteris director, who has not been a director of Iteris since September 2013, and one existing director of Iteris, who currently owns less than 2% of Maxxess' capital stock. Inventory Purchase Commitments At March 31, 2017, we had firm commitments to purchase approximately $6.7 million of inventory, operating assets and other supplies, which are expected to occur primarily during the first and second quarters of the fiscal year ended March 31, 2018.

As of March 31, 2017 and 2016, there were no outstanding shares of preferred stock, and we do not currently have plans to issue any shares of preferred stock. In August 2009, our Board of Directors adopted a stockholder rights plan, which calls for preferred stock purchase rights (each, a "Right") to be distributed, as a dividend, at the rate of one Right for each share of common stock held as of September 3, 2009. Each Right will entitle holders of common stock to buy one one-thousandth of one share of Series A Junior Participating Preferred Stock of Iteris. A further description and terms of the Rights are set forth in the Rights Agreement dated August 20, 2009 (as amended in August 2012) by and between Iteris and Computershare Trust Company, N.A., as rights agent. In connection with the stockholder rights plan, our Board of Directors approved the adoption of a Certificate of Designations, which created the Series A Junior Participating Preferred Stock, and likewise authorized the filing of a Certification of Elimination to eliminate the two series of junior participating preferred stock, which were originally created in April 1998 in connection with our previous stockholder rights plan which expired in 2008.

Employee Benefit Plans
Employee Benefit Plans	11. Employee Benefit Plans Stock Incentive Plans In September 2007, our stockholders approved the 2007 Omnibus Incentive Plan (the "2007 Plan"), which provides that options to purchase shares of our unissued common stock may be granted to our employees, officers, consultants and directors at exercise prices which are equal to or greater than the market value of our common stock on the date of grant. Options expire no more than ten years after the date of grant and generally vest at the rate of 25% on each of the first four anniversaries of the grant date. The 2007 Plan also allows for the issuance of stock appreciation rights, restricted stock, restricted stock units ("RSUs") and other stock-based awards based on the value of our common stock. New shares are issued to satisfy stock option exercises and share issuances under the 2007 Plan. In September 2009, our stockholders approved an amendment to increase the number of shares of our common stock authorized and reserved for issuance under the 2007 Plan by 800,000 shares to a total of 1,650,000 shares. In September 2012, our stockholders approved an amendment to increase the number of shares of our common stock authorized and reserved for issuance under the 2007 Plan by 800,000 shares to a total of 2,450,000 shares. In October 2014, our stockholders approved an amendment of the 2007 Plan to increase the number of shares of common stock authorized for issuance under the 2007 Plan by an additional 1,500,000 shares to a total of 3,950,000 shares. In September 2015, our stockholders approved an amendment of the 2007 Plan to increase the number of shares of common stock authorized for issuance under the 2007 Plan by an additional 1,000,000 shares to a total of 4,950,000 shares. In December 2016, our stockholders approved the 2016 Omnibus Incentive Plan (the "2016 Plan") which allows for the issuance of stock options, stock appreciation rights, restricted stock, RSUs", cash incentive awards and other stock-based awards to our employees, officers, consultants and directors at exercise prices which are equal to or greater than the market value of our common stock on the date of grant. Options expire no more than ten years after the date of grant and generally vest at the rate of 25% on each of the first four anniversaries of the grant date. Stock appreciation rights, restricted stock, RSUs and other stock-based awards are based on the value of our common stock. New shares are issued to satisfy stock option exercises and share issuances under the 2016 Plan. We currently maintain both the 2007 Plan and the 2016 Plan. Of these plans, we may only grant future awards from the 2016 Plan. As of the 2016 Annual Meeting of Stockholders, no future shares could be granted under the 2007 Plan. At March 31, 2017, there were approximately 2.4 million shares of common stock available for grant under the 2016 plan. As of March 31, 2017, options to purchase approximately 2,942,000 shares of common stock, as well as 93,000 RSUs, were outstanding under the 2007 Plan and options to purchase approximately 835,000 shares of common stock, as well as 139,000 RSUs, were outstanding under the 2016 Plan.

RSUs granted under the 2007 Plan vest at the rate of 25% on each of the first four anniversaries of the grant date provided that the holder remains in service (as defined by the 2007 Plan) as of the vesting date. RSUs granted under the 2016 Plan vest at varying terms between one and four anniversaries of the grant date provided that the holder remains in service (as defined by the 2016 Plan) as of the vesting date. The fair value per RSU is determined based on the closing market price of our common stock on the grant date.

This expense is currently expected to be recognized over a weighted average period of approximately 2.8 years for stock options and 1.8 years for RSUs. If there are any modifications or cancellations of the underlying unvested awards, we may be required to accelerate, increase or cancel any remaining unearned stock-based compensation expense. Future stock based compensation expense and unearned stock-based compensation will increase to the extent that we grant additional stock options, RSUs or other stock-based awards.

No contributions were made during the fiscal years ended March 31, 2017, 2016 and 2015. We sponsor a defined contribution 401(k) plan (the "401(k) Plan"), adopted in 1990, under which eligible associates voluntarily contribute to the plan, up to IRS maximums, through payroll deductions. We match up to 50% of contributions, up to a stated limit, with all matching contributions being fully vested after three years of service. Our matching contributions under the 401(k) Plan were approximately $881,000, $716,000 and $495,000 for the fiscal years ended March 31, 2017, 2016 and 2015, respectively.

Stock Repurchase Program
Stock Repurchase Program	12. Stock Repurchase Program In August 2011, our Board of Directors approved a stock repurchase program pursuant to which we were authorized to acquire up to $3 million of our outstanding common stock from time to time through August 2012. We repurchased approximately 964,000 shares under this original program for a total purchase price of $1.3 million. On August 9, 2012, our Board of Directors cancelled the initial stock repurchase program and the approximate $1.7 million of remaining funds, and approved a new stock repurchase program pursuant to which we may acquire up to $3 million of our outstanding common stock for an unspecified length of time. Under the new program, we may repurchase shares from time to time in open market and privately negotiated transactions and block trades, and may also repurchase shares pursuant to a 10b5-1 trading plan during our closed trading windows. There is no guarantee as to the exact number of shares that will be repurchased. We may modify or terminate the repurchase program at any time without prior notice. On November 6, 2014, our Board of Directors approved a $3.0 million increase to the Company's existing stock repurchase program, pursuant to which the Company may continue to acquire shares of its outstanding common stock from time to time for an unspecified length of time. For our fiscal year ended March 31, 2017, we did not repurchase any shares. For our fiscal year ended March 31, 2016 and 2015, we repurchased approximately 656,000 and 473,000 shares of our common stock, respectively. From inception of the program in August 2011 through March 31, 2017, we repurchased approximately 3,422,000 shares of our common stock for an aggregate price of approximately $5.6 million, at an average price per share of $1.63. As of March 31, 2017, all repurchased shares have been retired and returned to their status as authorized and unissued shares of our common stock. As of March 31, 2017, approximately $1.7 million remains available for the repurchase of our common stock under our current program.

Business Segments, Significant Customer and Geographic Information
Business Segments, Significant Customer and Geographic Information	13. Business Segments, Significant Customer and Geographic Information Business Segments We currently operate in three reportable segments: Roadway Sensors, Transportation Systems, and Agriculture and Weather Analytics (formerly known as Performance Analytics). The Roadway Sensors segment provides hardware and software products to multiple segments of the ITS market. These products primarily consist of various vehicle detection and information systemse used for traffic intersection control, communication and roadway traffic data collection applications. These include, among other products, our Vantage, VantageNext, VersiCam, Vantage Vector, SmartCycle, PedTrax, SmartSpan, Pegasus, Velocity, and P-series, products. The Transportation Systems segment includes transportation engineering and consulting services, and the development of transportation management and traveler information systems for the ITS industry. As of April 1, 2016, our performance measurement and information management solution, iPeMS, and related traffic analytic consulting services, previously included in Agriculture and Weather segment, were reassigned to the Transportation Systems segment to better align our traffic analytics capabilities, resources and initiatives. Prior segment information has been recast to reflect this change. The Agriculture and Weather Analytics segment includes ClearPath Weather, our road-maintenance applications, and ClearAg, our precision agriculture solutions. ClearPath Weather provides winter road maintenance recommendations for state agencies, municipalities and for commercial companies. Our ClearAg platform provides access to a comprehensive database of weather, soil and agronomic information combined with proprietary land-surface modeling and machine learning are essential to making informed agricultural decisions and is delivered through ClearAg solutions, including our ClearAg APIs and components, WeatherPlot mobile application, and ClearAg Insights applications. The accounting policies of our reportable segments are the same as those described in the summary of significant accounting policies (Note 1). Certain corporate general and administrative expenses, including general overhead functions such as information systems, accounting, human resources, marketing, compliance costs and certain administrative expenses, as well as interest and amortization of intangible assets, are not allocated to the segments. The reportable segments are each managed separately because they manufacture and distribute distinct products or provide services with different processes. All reported segment revenues are derived from external customers. Our Chief Executive Officer, who is our chief operating decision maker ("CODM"), reviews financial information at the operating segment level. Our CODM does not review assets by segment in his resource allocation, and therefore assets by segment are not disclosed below. Selected financial information for our reportable segments for the fiscal years ended March 31, 2017, 2016 and 2015 is as follows: Roadway Transportation Agriculture Total (In thousands) Year Ended March 31, 2017 Revenues $ $ $ $ Depreciation Loss on impairment of goodwill — — Segment income (loss) ) Year Ended March 31, 2016 Revenues $ $ $ $ Depreciation Segment income (loss) ) Year Ended March 31, 2015 Revenues $ $ $ $ Depreciation Segment income (loss) ) The following table reconciles total segment income to consolidated income from continuing operations before income taxes: Year Ended March 31, 2017 2016 2015 (In thousands) Segment income: Total income from reportable segments $ $ $ Unallocated amounts: Corporate and other expenses ) ) ) Amortization of intangible assets ) ) ) Change in fair value of contingent acquisition consideration — — ) Other (expense) income, net ) ) Interest income, net ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Loss from continuing operations before income taxes $ ) $ ) $ ) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Significant Customer and Geographic Information We currently have, and historically have had, a diverse customer base.

For Fiscal 2016, no individual customer represented approximately 10% of our total revenues. For Fiscal 2015, one individual customer represented approximately 10% of our total revenues and no other individual customer represented greater than 10% of our total revenues. No individual customer or government agency had a receivable balance at March 31, 2017 or 2016 greater than 10% of our total trade accounts receivable balances as of March 31, 2017 and 2016, respectively.

Description of Business and S21

Description of Business and Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Mar. 31, 2017
Description of Business and Summary of Significant Accounting Policies
Basis of Presentation	Basis of Presentation Our consolidated financial statements include the accounts of Iteris, Inc. and its subsidiary and have been prepared in accordance with generally accepted accounting principles in the United States of America ("GAAP"). All intercompany accounts and transactions have been eliminated in consolidation. The results of continuing operations for all periods presented in the consolidated financial statements exclude the financial impact of a discontinued operation. See Note 3, "Sale of Vehicle Sensors," for further discussion related to the discontinued operation presentation.
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires our management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements, and reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant estimates made in the preparation of the consolidated financial statements include the collectability of accounts receivable and related allowance for doubtful accounts, projections of taxable income used to assess realizability of deferred tax assets, warranty reserves, costs to complete long-term contracts, indirect cost rates used in cost-plus contracts, contract reserves, the valuation of purchased intangible assets and goodwill, the valuation of equity instruments and estimates of future cash flows used to assess the recoverability of long-lived assets and the impairment of goodwill and fair value of our stock option awards used to calculate the stock-based compensation.
Revenue Recognition	Revenue Recognition Product revenues and related costs of sales are recognized when all of the following criteria are met: (i) persuasive evidence of an arrangement exists, (ii) delivery under the terms of the arrangement has occurred, (iii) the price to the customer is fixed or determinable, and (iv) collection of the receivable is reasonably assured. These criteria are typically met at the time of product shipment but, in certain circumstances, may not be met until receipt or acceptance by the customer. Accordingly, at the date revenue is recognized, the significant obligations or uncertainties concerning the sale have been resolved. Transportation Systems revenues are derived primarily from long-term contracts with governmental agencies. Certain Agriculture and Weather Analytics revenues are also derived from long-term contracts with governmental agencies, as well as contracts with commercial companies. Agriculture and Weather Analytics revenues that are derived from contracts with commercial companies are from subscription revenue that we typically invoice our customers at the beginning of the term, in multiyear, annual, semi-annual or quarterly installments and revenue is recognized ratably over the period of the subscription beginning once all requirements for revenue recognition have been met, including provisioning the service so that it is available to our customers. When appropriate, revenues are recognized using the percentage of completion method of accounting, whereby revenue is recognized as contract performance progresses and is determined based on the relationship of costs incurred to total estimated costs. Any anticipated losses on contracts are charged to earnings when identified. Changes in job performance and estimated profitability, including those arising from contract penalty provisions and final contract settlements, may result in revisions to costs and revenues, and are recognized in the period in which the revisions are determined. Profit incentives are included in revenues, when their realization is reasonably assured. Certain of our revenues are recognized as services are performed and amounts are earned, which is measured by time incurred or other contractual milestones or output measures. Revenues accounted for in this manner generally relate to certain fixed fee professional services, cost plus fixed fee or time and materials contracts. Revenues for ongoing operations and maintenance services contracts are generally accounted for ratably as the services are performed throughout the term of the contract. Payments received in advance of services performed are deferred and recognized when the related services are performed. We recognize revenue from the sale of deliverables that are part of a multiple element arrangement in accordance with applicable accounting guidance that establishes a relative selling price hierarchy permitting the use of an estimated selling price to determine the allocation of arrangement consideration to a deliverable in a multiple element arrangement where neither vendor specific objective evidence ("VSOE") nor third party evidence ("TPE") of fair value is available for that deliverable. In the absence of VSOE or TPE of the stand-alone selling price for one or more delivered or undelivered elements in a multiple element arrangement, we are required to estimate the selling prices of those elements. Overall arrangement consideration is allocated to each element (both delivered and undelivered items) that has stand-alone value based on their relative selling prices, regardless of whether those selling prices are evidenced by VSOE or TPE or are based on our estimated selling prices.
Unbilled Accounts Receivable	Unbilled Accounts Receivable Unbilled accounts receivable in the accompanying consolidated balance sheets represent unbilled amounts earned and reimbursable under services sales arrangements, including approximately $362,000 of costs and estimated earnings in excess of billings on uncompleted contracts accounted for under Financial Accounting Standards Board ("FASB") Accountind Standards Codification ("ASC") 605-35, Construction-Type and Production-Type Contracts . At any given period-end, a large portion of the balance in this account represents the accumulation of labor, materials and other costs that have not been billed due to timing, whereby the accumulation of each month's costs and earnings are not administratively billed until the subsequent month. Also included in this account are amounts that will become billable according to contract terms, which usually require the consideration of the passage of time, achievement of milestones or completion of the project
Deferred Revenue	Deferred Revenue Deferred revenue in the accompanying consolidated balance sheets is comprised of cash collected from customers and billings to customers on contracts in advance of work performed, advance payments negotiated as a contract condition, estimated losses on uncompleted contracts, project-related legal liabilities and other project-related reserves, including approximately $798,000 of billings in excess of costs and estimated earnings on uncompleted contracts accounted for under FASB ASC 605-35. The unearned amounts are expected to be earned within the next twelve months. We record provisions for estimated losses on uncompleted contracts in the period in which such losses become known. The cumulative effects of revisions to contract revenues and estimated completion costs are recorded in the accounting period in which the amounts become evident and can be reasonably estimated. These revisions can include such items as the effects of change orders and claims, warranty claims, liquidated damages or other contractual penalties and adjustments for contract closeout settlements.
Concentration of Credit Risk	Concentration of Credit Risk Financial instruments that potentially subject us to a concentration of credit risk consist principally of cash and cash equivalents and trade accounts receivable. Cash and cash equivalents consist primarily of demand deposits and money market funds maintained with several financial institutions. Deposits held with banks may exceed the amount of insurance provided on such deposits. Generally, these deposits may be redeemed upon demand and are maintained with high quality financial institutions, and therefore are believed to have minimal credit risk. Our accounts receivable are primarily derived from billings with customers located throughout North America, as well as in the Middle East, Europe, South America and Asia. We generally do not require collateral or other security from our domestic customers. We maintain an allowance for doubtful accounts for potential credit losses, which losses have historically been within management's expectations. We have historically had a diverse customer base. For the fiscal year ended March 31, 2017 ("Fiscal 2017"), one individual customer represented greater than 10% of our total revenues. For the fiscal year ended March 31, 2016 ("Fiscal 2016") and the fiscal year ended March 31, 2015 ("Fiscal 2015"), no individual customer represented more than 10% of our total revenues.
Fair Values of Financial Instruments	Fair Values of Financial Instruments The fair value of cash equivalents, receivables, accounts payable and accrued expenses approximate carrying value because of the short period of time to maturity.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents consist of cash and short-term investments with initial maturities of ninety days or less.
Prepaid Expenses and Other Current Assets	Prepaid Expenses and Other Current Assets Prepaid expenses and other current assets were $2.1 million as of March 31, 2017 and $1.5 million as of March 31, 2016 and included approximately $535,000 of cash designated as collateral on performance bonds, as required under certain of our Transportation Systems contracts in the Middle East. The performance bonds require us to maintain 100% cash value of the bonds as collateral in a bank that is local to the purchasing agency. The performance bond collateral is required throughout the delivery of our services and is maintained in the local bank until the contract is closed by the purchasing agency. We expect these requirements, and the related cash collateral restrictions, to be released during 2017.
Allowance for Doubtful Accounts	Allowance for Doubtful Accounts The collectability of our accounts receivable is evaluated through review of outstanding invoices and ongoing credit evaluations of our customers' financial condition. In cases where we are aware of circumstances that may impair a specific customer's ability to meet its financial obligations subsequent to the original sale, we will record an allowance against amounts due, and thereby reduce the net recognized accounts receivable to the amount we reasonably believe will be collected. We also maintain an allowance based on our historical collections experience. When we determine that collection is not likely, we write off accounts receivable against the allowance for doubtful accounts.
Inventories	Inventories Inventories consist of finished goods, work-in-process and raw materials and are stated at the lower of cost or market. Cost is determined using the first-in, first-out method.
Property and Equipment	Property and Equipment Property and equipment are recorded at cost and are depreciated using the straight-line method over the estimated useful life ranging from three to eight years. Leasehold improvements are depreciated over the term of the related lease or the estimated useful life of the improvement, whichever is shorter.
Goodwill and Long-Lived Assets	Goodwill and Long-Lived Assets We evaluate goodwill on an annual basis in our fourth fiscal quarter or more frequently if we believe indicators of impairment exist. We have determined that our reporting units for purposes of testing for goodwill impairment are identical to our reportable segments for financial reporting purposes. We first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If we conclude that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, we conduct a goodwill impairment test. The impairment test involves comparing the fair values of the applicable reporting units with their carrying values. We determine the fair values of our reporting units using the income valuation approach, as well as other generally accepted valuation methodologies. In Fiscal 2017, we adopted the provisions issued by the FASB that were intended to simplify goodwill impairment testing. This guidance permits us to eliminate the second step of the goodwill impairment test, and eliminate the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment. If the carrying amount of a reporting unit exceeds the reporting unit's fair value, the amount by which the carrying value of the goodwill exceeds its implied fair value, if any, is recognized as an impairment loss. We monitor the indicators for goodwill impairment testing between annual tests. As of March 31, 2017, we determined the carrying amount of the goodwill in the Agriculture and Weather Analytics reporting unit exceeded it's implied fair value, and as a result, recognized an approximate $2.2 million impairment loss in the accompanying consolidated financial statements. We also determinted that no adjustments to the carrying value of its goodwill and intangible assets were required in the Roadway Sensors and Transportation Systems reporting units. We test long-lived assets and purchased intangible assets (other than goodwill) for impairment if we believe indicators of impairment exist. We determine whether the carrying value of an asset or asset group is recoverable, based on comparisons to undiscounted expected future cash flows the asset or asset group is expected to generate. If an asset is not recoverable, we record an impairment loss equal to the amount by which the carrying value of the asset exceeds its fair value. We primarily use the income valuation approach to determine the fair value of our long lived assets and purchased intangible assets. As of March 31, 2017, there was no impairment to our long-lived and intangible assets.
Income Taxes	Income Taxes We utilize the asset and liability method of accounting for income taxes, under which deferred taxes are determined based on the temporary differences between the financial statement and tax basis of assets and liabilities using tax rates expected to be in effect during the years in which the basis differences reverse. A valuation allowance is recorded when it is more-likely-than-not that some or all of the deferred tax assets will not be realized, which increases our income tax expense in the period such determination is made. As such, we determined it was appropriate to record a valuation allowance of approximately $10.1 million in the third quarter of our Fiscal 2016 against our deferred tax assets. We will continuously reassess the appropriateness of maintaining a valuation allowance. Income tax positions must meet a more-likely-than-not recognition threshold to be recognized. Income tax positions that previously failed to meet the more-likely-than-not threshold are recognized in the first subsequent financial reporting period in which that threshold is met. Previously recognized tax positions that no longer meet the more-likely-than-not threshold are derecognized in the first subsequent financial reporting period in which that threshold is no longer met.
Stock-Based Compensation	Stock-Based Compensation We record stock-based compensation in our consolidated statements of operations as an expense, based on the estimated grant date fair value of our stock-based awards, whereby such fair values are amortized over the requisite service period. Our stock-based awards are currently comprised of common stock options and restricted stock units. The fair value of our common stock option awards is estimated on the grant date using the Black-Scholes-Merton option-pricing formula. While utilizing this model meets established requirements, the estimated fair values generated by it may not be indicative of the actual fair values of our common stock option awards as it does not consider certain factors important to those awards to employees, such as continued employment and periodic vesting requirements, as well as limited transferability. The fair value of our restricted stock units is based on the closing market price of our common stock on the grant date. If there are any modifications or cancellations of the underlying unvested stock-based awards, we may be required to accelerate, increase or cancel any remaining unearned stock-based compensation expense.
Research and Development Expenditures	Research and Development Expenditures Research and development expenditures are charged to expense in the period incurred.
Shipping and Handling Costs	Shipping and Handling Costs Shipping and handling costs are included as cost of revenues in the period during which the products ship.
Sales Taxes	Sales Taxes Sales taxes are presented on a net basis (excluded from revenues) in the consolidated statements of operations.
Advertising Expenses	Advertising Expenses Advertising costs are expensed in the period incurred and totaled $146,000, $164,000 and $134,000 in Fiscal 2017, Fiscal 2016 and Fiscal 2015, respectively.
Warranty	Warranty We generally provide a one to three year warranty from the original invoice date on all products, materials and workmanship. Products sold to various original equipment manufacturer customers sometimes carry longer warranties. Defective products will be either repaired or replaced, usually at our option, upon meeting certain criteria. We accrue a provision for the estimated costs that may be incurred for product warranties relating to a product as a component of cost of sales at the time revenue for that product is recognized. The accrued warranty reserve is included within accrued liabilities in the accompanying consolidated balance sheets.
Repair and Maintenance Costs	Repair and Maintenance Costs We incur repair and maintenance costs in the normal course of business. Should the repair or maintenance result in a permanent improvement to one of our leased facilities, the cost is capitalized as a leasehold improvement and amortized over its useful life or the remainder of the lease period, whichever is shorter. Non-permanent repair and maintenance costs are charged to expense as incurred.

Recent Accounting Pronouncements	Recent Accounting Pronouncements In May 2014, the FASB issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers ("ASU 2014-09"), which establishes principles for reporting revenue and cash flows arising from an entity's contracts with customers. This new revenue recognition standard will replace most of the recognition guidance within GAAP. This guidance was deferred by ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date, issued by the FASB in August 2015, and is now effective for fiscal years beginning on or after December 15, 2017 with early adoption permitted as of the original effective date. In March 2016, the FASB issued ASU No. 2016-08, Revenue from Contracts with Customers: Principal versus Agent Considerations , which further clarifies the implementation guidance in ASU 2014-09. In April 2016, the FASB issued ASU No. 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing , to expand the guidance on identifying performance obligations and licensing within ASU 2014-09. In May 2016, the FASB issued ASU 2016-12, Revenue from Contracts with Customers: Narrow-Scope Improvements and Practical Expedients , which amends the guidance in the new revenue standard on collectability, noncash consideration, presentation of sales tax, and transition. The amendments are intended to address implementation issues that were raised by stakeholders and provide additional practical expedients to reduce the cost and complexity of applying the new revenue standard. These standards are effective for fiscal years beginning after December 15, 2017, including interim periods within that reporting period. We anticipate that these standards will have an impact on our consolidated financial statements and we are still evaluating the significance of the impact. In July 2015, the FASB issued ASU No. 2015-11, Simplifying the Measurement of Inventory ("ASU 2015-11") to simplify the guidance on the measurement of inventory. Under the new standard, an entity should measure inventory at the lower of cost or net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The standard is effective for interim and annual periods beginning after December 15, 2016. We do not anticipate a significant impact on our consolidated financial statements upon adoption of ASU 2015-11. In November 2015, the FASB issued ASU No. 2015-17, Balance Sheet Classification of Deferred Taxes ("ASU 2015-17") to simplify the presentation of deferred taxes by requiring deferred tax assets and liabilities be classified as noncurrent on the balance sheet. ASU 2015-17 is effective for public companies for annual reporting periods beginning after December 15, 2016, and interim periods within those fiscal years. The standard may be adopted prospectively or retrospectively and early adoption is permitted. We early adopted ASU 2015-17, prospectively, in our fourth quarter of Fiscal 2016, which did not have a material impact on our consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases ("ASU 2016-02"). The pronouncement requires an entity to recognize assets and liabilities for the rights and obligations created by leases on the entity's balance sheet for both finance and operating leases. For leases with a term of 12 months or less, an entity can elect to not recognize lease assets and lease liabilities and expense the lease over a straight-line basis for the term of the lease. ASU 2016-02 will require new disclosures that depict the amount, timing, and uncertainty of cash flows pertaining to an entity's leases. Companies are required to adopt the new standard using a modified retrospective approach for annual and interim periods beginning after December 15, 2018. Early adoption of ASU 2016-02 is permitted. We are currently evaluating the impact of ASU 2016-02 on our consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-09, Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting ("ASU 2016-09"), which is intended to simplify several aspects of accounting for share-based compensation arrangements, including the income tax impact, classification on the statement of cash flows and forfeitures. The guidance will be effective for the fiscal year beginning after December 15, 2016, including interim periods within that year. We are currently evaluating the impact of ASU 2016-09 on our consolidated financial statements. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments ("ASU 2016-15"), which clarifies how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The new standard is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017, and early adoption is permitted. We are currently evaluating the impact of ASU 2016-15 on our consolidated financial statements. In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash ("ASU 2016-18"), requiring restricted cash and cash equivalents to be included with cash and cash equivalents on the statement of cash flows. The new standard is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017, with early adoption permitted. We are currently evaluating the impact of ASU 2016-18 on our consolidated financial statements. In December 2016, the FASB issued ASU No. 2016-19, Technical Corrections and Improvements ("ASU 2016-19"), which clarifies guidance, corrects errors and makes minor improvements affecting a variety of topics in the ASC. The new standard is effective upon issuance (December 14, 2016) for amendments that do not have transition guidance, with all other amendments effective for fiscal years, and interim periods within those years, beginning after December 15, 2016, with early adoption permitted. We are currently evaluating the impact of ASU 2016-19 on our consolidated financial statements. In December 2016, the FASB issued ASU No. 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers ("ASU 2016-20"), which allows entities not to make quantitative disclosures about remaining performance obligations in certain cases and requires entities that use any of the new or previously existing optional exemptions to expand their qualitative disclosures. The new standard is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017, with early adoption permitted. We are currently evaluating the impact of ASU 2016-20 on our consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment ("ASU 2017-04"), eliminating the second step of the goodwill impairment test, and eliminating the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment. The new standard is effective for fiscal years, and interim periods within those years, beginning after December 15, 2019, with early adoption permitted. We chose to early adopt ASU 2017-04 in our fourth quarter of Fiscal 2017, which had an impact on our consolidated financial statements, as we recognized a goodwill impairment loss in our Agriculture and Weather Analytics reporting unit.
